I appreciate the feedback. My daughter was accelerated a grade and it has worked very well, but she didn't have the same difficulty. Without going into details about my son, he does have significant social difficulties (he has some good friends, but also gets picked on and has severe pragmatic language delays). Things are complicated by the fact that he was subject accelerated for reading last year but is not being allowed to do that this year due to increasing social difficulty. So he is effectively repeating English language arts, which intensifies the problem of having difficulty being patient and of disliking school. It is very hard to know what is best for him.
